Hubs, Hubs, Hubs

My request is for someone to show pictures of every type of hub that exists and explain the pro’s and con’s of each.

I currently own an antique unknown brand uni that I bought around 30 years ago. It’s cranks are not 180 degrees apart from themselves and I’d like to attempt to correct it.

I also have a Torker CX that is 5-10 years old. It’s left crank is loosening up every 200 feet or so of riding. I’ve recently got advice from Torker tech support and will be trying it soon. They said to make sure the crank and spindle are cleaned of all grease with an evaporative solvent and torque the crank bolt to 20-26 ft pounds.

I would find the requested info very helpful and I’m sure many others would as well. It’s good stuff to know for maintenance and for deciding on the next uni to purchase.
